ADVERTISING DEVICE. 7

I Specificationof Letters Patent.

Application filed June 20, 1917. Serial No. 175,922;

T 0 all whom it may concern:

Be it known that I, CARRoL A. CORBETT,

a citizen of the United States, residing 'at Grand Rapids, in thecountyof Kent and State of Michigan, have invented certain new and usefulImprovements in Advertising Devices; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make anduse'the same.

My invention relates to improvements in advertising devices and moreparticularly to one Which is so constructed as to form a closure for.the coal holes commonly used in side walks and the like for dumpingcoalinto basements below, means being provided for illuminating thedevice at night so that the advertising matter thereon will beconspicuously displayed.

The object of the invention is to provide a device of the classdescribed which may be easily and inexpensively .manufactured andmarketed, yet one which will be highly efficient and durable and willinterfere in no manner with dumping coal through the coal hole after thedevice has been removed.

With the foregoing general object in view, the invention resides inthe'novel features of construction and unique combinations of parts tobe hereinafter fully described and claimed, the descriptive matter beingsupplemented by the accompanying drawings which form a partof thisspecification and in which:

Figure 1 is a top plan view of the device inuse;

Fig. 2 is a vertical section on the plane indicated by the line 2-2 ofFig. 15' Fig. 3 is a view similar to Fig. 2, but 1slhowingthe deviceremoved from-the coal ole;

Fig. 4 is an enlarged detail vertical'section of a portion of thedevice; and

Fig. 5 is a detail bottom plan view showing more particularly thedetachable connection between the supporting ring and the reflector. Inthe drawings above briefly described, the numeral 1 designates a portionof a sidewalk or the like having a coal hole 2 equipped with the usualcircular frame 3, the space circumscribed by said frame being usuallyclosed by the common type of cover,

- whereas in the present invention, it is closed by the device itself.This device includesa supporting ring 4 having a horizontallyextendingannular. flange 5 resting on the frame 3, the body portion of said ringbe-' ing received in said frame. .An internal Patented Jan. 1,1918.

annular rib 6 is formed onthe ring tbetween the upper arid lower edgesthereof, said rib supporting thereon a suitable lens or other.appropriate transparent plate 7, a gasket 8 being by preferenceinterposed between the two as shown. Anypreferred means could well beemployed for. securingthe transparent opaque plate 7 in place,-butcement is preferably run in between the edge of said plate andthe innerside of the ring as indicated at 9. By this provision, it is insuredthat no water shall leak through the device.

A plurality of headed studs 10, preferably in the form of screws, dependfrom the lower side of the rib 6 and eoact with keyhole slots 11, insecuring a substantially para-' bolic reflector 12 in place, said slotsbeing formed in a horizontal annular flange 12 positioned at the openupper end of the reflector as shown clearly in the drawings. By

this connection, it will be obvious that the reflector may be easilyattached and detached so that the electric bulb 14 within the reflectormay be renewed whenever required.

, The lamp 14 is carried in any appropriate, type of socket 15 which ismounted at the inner end of the reflector 12,. said socket having adetachable connection with a pair of current conducting wires 17 bymeans of a common type of plug 16. wires 17 are by'preference twistedtogether in the usualmanner and extend beneath the The twoside Walk orthe like 1 to any preferred source of current, said wires being ofsuflicient length to permit the entire device to be removed fromtheframe 3 before said operation to disconnect said wires so that theymay hang loosely and interfere in no manner with the dumping of coalthrough the coal hole.

When the deviceis removed, it is by pref erence inverted as will beclear from Fig. 3, and in order to prevent possible injury of the plate7, lugs 19 are preferably formed -on the upper side of the ring 4, sothat said -wires are detached, it being then a simple ployed'forobtaining the same results, the

invention being dependent in no manner upon such minor features ofconstruction.

advertising matter so that the same will be conspicuously displayed.From the foregoing, taken in connection with the accompanying drawing,it will be obvious that although my invention is of extremely simple andinexpensive construction, it will be ahighly efficient device for thepurpose intended. Since probably the best results are obtained from thespecific construction shown and described, such construction constitutesthe preferred form of the device. I wish it understood, however,

In either case, when the bulb 14 is that within the scope ofthe'invention as claimed numerous minor changes may well be made.

I claim:

An advertising device comprising a ring positioned remova'biy in a sideWalk coal saidreflector, and flexible current conduct-t ing wires belowthe side walkand having a plug detachably enga ed with said socket.

In testimony whereo I have hereunto set my hand in the presence of asubscribing witness.
